Retrieving results for functional units has been problematic because Functional unit results don't fit neatly within the three main criteria (NetworkElement - which maps to catchment, RecordingElement and RecordingVariable).
Long story short - the typical behaviour is that you get N subcatchments M functional units M functional units.
So, in the example here, 10 catchments, 5 functional units leads to 10 x 5 x 5 = 250 time series being retrieved, rather than the expected 50.
This can partly be dealt with by using an appropriate column naming function (veneer.name_for_fu_and_sc) and then filtering the results, but its still annoying, slow and wastes memory.
In recent versions of Veneer, you can now request results for a specific Functional Unit. You need to call v.retrieve_multiple_time_series multiple times, but you end up with just what you're after

Recent versions of Veneer support the FunctionalUnit criteria. Note this is only available on retrieve_multiple_time_series - not available on configure_recording.
This version is bundled with Source 4.6 onwards and available in custom Veneer builds for earlier versions of Source
